The multi-soliton solutions with three arbitrary even or odd functions are found from the ■_s^x■_d symmetry reductions of a coupled local KP system. The result shows that for the ABKP equation with ■_s^x■_d nonlocality, the odd numbers of solitons are prohibited.The solitons of the ABKP must be paired. For the ABKPⅡ equation, there exists a critical value of wave numbers for the existence of paired solitons. For the ABKPI equation, there are two types of 'breather' excitations. A lump solution of the ABKPI may possess four, five or six leaves.展开更多

Electroweak symmetry breaking is realized via the Coleman-Weinberg mechanism in a classically scale invariant theory, while the neutrino mass is generated radiatively through interactions with dark matter in a typically scotogenic manner. The model introduces a scalar triplet and singlet and a vector-like fermion doublet that carry an odd parity of Z2, and an even parity scalar singlet that helps preserve classical scale invariance. We sample over the parameter space by taking into account various experimental constraints from the dark matter relic density and direct detection, direct scalar searches, neutrino mass, and charged lepton flavor violating decays. We then examine by detailed simulations possible signatures at the LHC to find some benchmark points of the free parameters. We find that the future high-luminosity LHC will have a significant potential in detecting new physics signals in the dilepton channel.展开更多

Its ground state(GS) spin ordering is analyzed by minimizing its energy. Our analytical derivations show that all the spins in the GS phase must lie in planes that are parallel to each other. When applying the derived formulations to concrete lattices such as the square and simple cubic lattices, we find that in the large J2 region, a large continuous GS degeneracy concluded by a qualitative analysis is lifted, and collinear striped ordering is selected as the GS phase.展开更多

Furthermore, it lost the sustained acceleration cues of high-and mid-frequency in cross-over(tilt-coordination) channel, and the acceleration of cross-over frequency was also limited by angular velocity limiter, so the false cues in flight simulation process were clearly perceived by pilots. The paper studied the characteristics of the classical washout algorithm and flight simulator motion platform, tried to redesign the source of cross-over acceleration channel and translation acceleration channel, and transferred the part of cross-over acceleration that was unsimulated sustained acceleration to translation acceleration channel. Comparisons were mainly made between classical washout algorithm and revised algorithm in a longitudinal/pitch direction. The evaluation was based on the implementation of human vestibular perception system. The results demonstrated that the revised algorithm could significantly reduce the phase lag, and improved the spikes tracking performance. Furthermore, sensory angular velocity and the error of sensory acceleration were strictly controlled within the threshold of human perception system, and the displacement was a little broader than the classical washout algorithm. Therefore, it was proved that the new algorithm could diminish the filters parameters and heighten the self-adaptability for the washout algorithm. In addition, the magnitude of false cues was remarkably reduced during flight simulator, and the workspace utilization of the motion platform was developed by "closed-loop" control system.展开更多

But there is little information on the recombination in natural populations of CSFVs. Therefore, a phylogenetic analysis of 62 fulllength genome CSFV strains, isolated from all over the world, was performed to detect potential recombination events, with the recombinant sequences being analyzed with the SimPlot and RDP programs. The results identified a mosaic virus, Chinese CSFV HCLV(2)(AF091507.1), which is the one naturally emerged recombinant CSFV with two recombination breakpoints at 2 484 and 2 900 bp of the genome alignment. Its two putative parental-like strains were CSFV Shimen(AF092448.2) and CSFV strain C/HVRI(AY805221.1). This work demonstrated that homologous recombination did occur in natural CSFV populations. It had significant implications for understanding the molecular epidemiology of CSFV, and revealed that recombination was an important factor for high genetic diversities of CSFV.展开更多

He reasoned that the amount of classical information required to describe a quantum system scaled exponentially with its size, and thus could not be efficiently simulated by a classical computer. Indeed, a fairly modest system of 100 quantum bits would already require more information to describe than all the present data storage on Earth[1].展开更多

The results showed that the homology of the nucleotide sequences of protein N was 99.7% between the isolate and the classical strains (VR2332 and SD1), and 93.4% between the isolate and the highly pathogenic strains (JXA1, HuN4, SX-1 and TJM). The results suggested that the virus was classical PRRSV in the pig farm. The research would provide a reference for the diagnosis and targeted therapy of classical PRRSV infection in swine production.展开更多
